ddev snapshot restore should take either full name of snapshot or shortname

[shaal]

Describe the bug

I can no longer restore snapshots with the same name I used when I created them.

Previously, (up until ddev v.1.18), I could backup and restore snapshots with these commands:
Create new snapshot - ddev snapshot -n name_of_snapshot
Restore a snapshot - ddev snapshot restore -n name_of_snapshot

In ddev v1.19 alpha3, the snapshot's name has a new suffix, of the db-type and db-version:
e.g. name_of_snapshot-mariadb_10.3.gz

To Reproduce

Run these commands, in ddev v1.18 it works, but in ddev v1.19 that functionality is broken -
ddev snapshot -n hello-world
ddev snapshot restore -n hello-world

Expected behavior

Similar to version 1.18, I think users expect using the same name in snapshot backup and restore commands.

I agree this is some friction that should be removed. Thanks for testing, and thanks for the issue!
